tty: cyclades: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list
pointer to all timer callbacks, switch to using the new timer_setup() and
from_timer() to pass the timer pointer explicitly. Moves timer structures
from global to attached to struct cyclades_port.
